Murder at High Tide

It was high tide when Dan Parados was murdered in his library. And the next day, the only man with a real clue to the murderer died in that same library, again as the high tide pounded against the rocky shore.

There were seven people staying with Parados on his island off the California coast. More than one had hated Dan Parados and had real motives for murdering this man, who lived like some great leech draining the blood of others. Fascinating Caroline Brent had a stronger motive than the others, perhaps, for Parados had ruined her family and had even ruthlessly seized the family heirlooms. So, Anatole Flique, the suave and imperturbable Paris detective listened with suspicion to the explanation of her presence under Parados' roof.

Then begins a game of wits among those tense people on San Lucas Island, the detective implacable in following the trail of the murderer wherever it may lead, and Allen Hunt, the young antiquarian working with him, yet determined to prove Caroline Brent's innocence. They quickly turn up intrigue, crime, hatred, and a twenty-year-old mystery. But who was the murderer? And why were the murders committed when the tide was high?

Murder at High Tide was published in 1930.
